PHOTOGRAPHIC-PEENT-WASHING IVL'ACHINE.

Application filed July 27, 1920.

To all 107mm it may concern:

it known that we, lniiNo Po'r'rnUoK and Norman SHALIT, the former a citizen of the United States and the latter a citizen f l-iussia. residing at New York city, in the county low York and State of New York, have invented certain new and useful lin- 'irovem'ents in Photo raphic-Print-ll ashin t Machines, of which tne following is a specification.

This invention has relation to photographic print washing; machines, and has for an object to provide a machine for the purposc of washing photographic prints or the like and consists of a plurality of rotatable elements in which the prints are enclosed and which are oesipjned to rotate in bath, with a specific power mechanism operating}; upon the friction transmission principle for the purpose of communicating rotary motion to said rotatable elements with means for disconnecting communication when de sired.

A still further object of the invention is to provide a photographic print washing ma chine of the character above set forth comprising a plurality of rotatable drums in which the prints are enclosed and rotated in a bath, said drums being mounted in such a manner that they may be independently clevated to a position above the bath when do sired for the purpose of removing the washed prints or for charging; the drum.

in addition to the foregoing this invention comprehends improvements in the details of construction and arrangement of parts to he hereinafter described and particularly set forth in the appended claims.

in the accompanying drawings in which similar and corresponding parts are designated by the same characters of reference throughout the several views in which they appear.

Figure 1 is a view of the machine in frontelevation with the tank and supporting members shown in section.

Figure 2 is a view thereof in top plan.

Figure 3 is a view of the machine in transverse section. and

Figure 4 is a'detail view.

Figure 5 is a detail perspective view.

vl ith reference to the drz-iwings indicates a trough like receptacle in which the bath is contained. said trough being substantially semi-circular and supported upon Serial No. 399,383.

three members, more or less, each supporting member consisting of a vertical portion 11, a horizontal bent portion 12 extending beneath the trough and another vertical portion supporting the forward side of the trough. The upper ends of the members 11 are connected by a horizontal bar as shown. An overflow pipe 14 is provided which is located horizontally and longitudinally of the trough adjacent the upper and rear edge thereof as shown. This pipe is perforated at places to draw away the excess water when the same has reached a desired level. The pipe 1.4 also serves as a support for rectangular frames 15 of which three are provided. Each frame consists of the longitudinal members 16 and the transverse memhere 17, each member 17 having its rear end formed with a semi-circular portion 18 which rests upon the pipe 1 1 while the opposite ends of the members 17 are designed to rest upon the edge of the trough. The intermediate portions of the members 17 are offset as at 19 to form a support for ball bearing cages 20. Within. each frame 15 there is located a drum 21 of foraminous material, each drum having a pair of end trunnions 22 which rests in the ball bearing cages and thus support the drums for rotation. One or both ends of each drum as desired formed of a metallic band of a purpose to be presently noted. A supporting device is also provided which consists of a twisted partly curved bar 2 1 having its forward end pivoted to the intermediate portion of the forward member 16 of each frame. 15. Ohviously, three of said bars 24 will be provided as in the present instance and the rear end of each bar 2% operates in a slot formed in the connecting bar 13. The slot it will. be noted is out from the top edge of said bar; and to close the upper end of said slot we provide connecting members 25 which are bolted to the members 13 as shown. When the frame 15 is in a lowered position it is supported upon the forward edge of the trough as explained above. However, when the frame has been elevated it may be supported in an elevated position by reason of the fact that the edge of the member 13 may rest in a slot 25 formed in the underside of each bar 24, as shown in dotted lines in Figure 3. .We also provide an inlet which consists of a pipe 27 located in the bottom of the trough, extending longitudinally thereof and mounted in bearings 29 which in turn are 10- cated upon'the upper ends of the members l1. The shaft carries three relatively small pulleys 30 around which belts 31 are trained the belts also passing around relatively large pulleys 32 which are mounted upon stubshafts 33. Each stub-shaft is supported in a swingingearm 84-, the opposite end of each arm being supported upon the shaft 28 so as to swin in a vertical are. To the oppositeend of each shaft 33 there is mounted a friction wheel 35 which is preferably constructed of wood and designed to bear upon the end band 23 of the drum. One end of the shaft 28, is provided with a pulley around which a belt passes, said pulley being indicated at 36. The pulley is intended to be driven by motor, hand power or any other method desired or found convenient.

It will be readily seen. that when the drums are in a lowered position and partly submerged within the bath with the friction members restingthereupom any power transmitted to the shaft 28 will be communicated through thebelt 31 to thewheels 32 and friction pulleys thus rotating the drum. The prints are previously inserted in the drums through a door opening which is normally closed by means of a hinged door 37. Said door may beheld in closed position through any convenient form of catch or lock. -The water issuing through the perforations of the tube 2'? will be directed down wardly and upwardly and circulate around" the drum during rotation the e Y of thoroughly washing the prints contained therein. Whein it is desired any one of the drums may be elevated by hand and retained in elevated position through. the medium. of the bar 24-. in the man- 'ner described.- Also, power may be disconneeted from any one of the drums if desired by merely lifting the arm 34: corresponding to said drum. To hold the arm 34- in elevated' -position we provide a curved support SSfwhich is pivoted to the under side of the member'34c and extends through an opening in the bar 13"- The underside of each member 38 isprovidedwith a slot 38 so that when the bar 34: is raised said slot may receive the edge ofthe member 13 to thus relarity, we realize that in practice various alterations therein may be made. We therefore reserve the right and privilege of changthe form of the details or otherwise ali ng the arrangement of the correlated parts without departing from the spirit of the invention or the scope of the appended claims.

Having thus described our invention what we claim as new and desire to secure by- United States Letters Patent is l.
